Gold margin and FCF

Has anyone else tried to put some figures on the FCF potential of PGO, across both Tom's and Rustlers, in current gold price environment?

I've started a back of the envelope, interested for others to poke holes in it or expand as required. Couldn't find a solid number for Rustlers proposed production level, so estimate based on the historical in mid-90's and what would seem reasonable;

	Column 1	Column 2	Column 3	Column 4
0			Toms	Rustler
1	prodn	ozpa	65,000	50,000
2	AISC	$/oz	$985	$1,100
3	POG	$/oz	$1,795	$1,795
4	margin	$/oz	$810	$695
5	FCF	$pa	$52,650,000	$34,750,000
6	FCF total	$pa	$87,400,000

food for thought! explains why we are seeing solid support at and above 9c which is still only a $40m odd market cap
